Answer 1

Sum of the three angles of a triangle = 180 degrees.

Answer 2

so i would just divide 180 by 3?

Answer 3

Can you post a screenshot of the problem?

Answer 4

yes, 1 sec

Answer 5

Okay, it is not necessary.

Answer 6

Let m<A = x
m<B = 2m<A = 2 * x = 2x
m<C = 3m<A = 3 * x = 3x

Sum of three angles of a triangle = 180 degrees.
Therefore, x + 2x + 3x = 180
6x = 180
x = 30

m<A = x = 30 degrees
m<B = 2x = 2*30 = 60 degrees
m<C = 3x = 3*30 = 90 degrees

Answer 8

okay so 17 would be
m<A=x+10
m<B=x
m<C=2x-10?

Answer 9

For 17, make m<A = x

Answer 10

m<A = x
m<B = m<A + 10 = x + 10
m<C = 2m<A - 10 = 2x - 10

x + x + 10 + 2x - 10 = 0
solve for x.
Put it back in the three angles and calculate them.

Answer 11

wouldnt it =180?
